July 30, 1935. H. WOOTTON PAPER CONTAINER Filed Feb. 25, 1955 PatentedJuly 30, 1935 UNITED STATES PATENT OFFICE PAPER CONTAINER Harry Wootton,Upper Montclair, N. 1., assignor to Mono Service 00., Newark, N. I.

This invention relates to paper containers such as are described in theapplications already filed in the names of Elmer Zebley Taylor, SerialNo. 570,427, dated October 22, 1931, Edmund Paul Herrmann, Serial No.632,598, dated September.

10, 1932, and EdmundPaul Herrmann, Serial No. 649,648, dated December30, 1932, and comprising in each case a conical double-walled body inone end of which a closure is secured. After filling a closure is to beapplied to the other end, and special means are described in each of thesaid prior applications for subsequently opening the container,consisting in the formation of weakening lines around that part oi theblank which forms that end of the body at which the container is to beopened, so that the portion between such weakening lines can separatingthe end of the. body with the closure secured therein from the main bodyof the container and exposing the contentsfor use as required.

In the preferred formdescribed in the prior applications above referredto the container is to be opened at the smaller end, but in the presentinvention the container is to be opened at the larger end, and theconstruction is such that the,

removed end with the closure secured therein can be very convenientlyused as a cover for the container if all the contents have not beenremoved.

The invention is illustrated in the accompanying drawing, in which Fig.1 represents on an enlarged scale a portion of the upper end of a filledcontainer; Fig. 2 shows the upper end of such container separated and inuse as a cover; Fig. 3 shows a modified arrangement in which a differentform of end closure is employed, and Figs.

4, and 6 suitable arrangements of the weakening lines on the body blank.

In carrying out the present invention a blank I is employed for theconical body in which weakening lines 3, 4, are formed, which may bearranged as shown for example in either of the ways illustrated in Figs.4, 5 and 6. In Fig. 4 it will be seen that, as described in Elmer ZebleyTaylor's prior application No. 570,427 above referred to, the line 3extends parallel with the edge of the blank i throughout the wholelength thereof, and that line 4 is also parallel with such edge in thepart which forms the inner wall of the container and then widens out andextends spirally along the part constituting the outer wall, and'that atab 5 is left on the edge of the blank between the outer ends of theweakening lines 3, 4. When this arrangement is employed it is necessaryin tearing out the strip between be torn out, thus the weakening linesto open the container to make two complete turns around the latter, butif the arrangements of weakening lines shown in Figs. 5 and 6 areemployed the entire strip 6 can be torn out by a single turn around thecontainer. 5

In Fig. 5 the weakening lines 3, 4, are arranged as described in thespecification of Edmund Paul Herrmanns prior United States applicationSerial No. 632,598, the line 3 being againparallel with the edge ofblank I throughout its length, and 10 line 4 also parallel therewiththroughout its length but spaced farther away from line 3 in the portionforming the outer wall of the body of the container than in the portionforming the inner wall, and a cut i being made at a suitable pointbetween the weakening lines to form a tab by which both portions of thestrip 6 canbe torn out in one turn around the container.

Fig. 6 shows the arrangement described in Edmund Paul Herrmanns priorUnited States ap plication Serial No. 649,648, in which line 3 is againparallel with the edge of blank I, and line 4 also parallel therewith inthe portion forming the inner wall, and then extending spirally aroundthe part forming the outer wall, a tab 5 being left 2 on the edge of theblank as in the arrangement shown in Fig. 4. A cut 8 is made at a pointwhich when the blank is rolled up to form the conical body of thecontainer comes immediately beneath the tab 5, and the adhesive employedis in this case applied to the part of the inner wall adjacent to thiscut 8, so that when the tab' is pulled to open the container theadhesion between the inner and outer parts of strip 6 will cause themboth to be torn out at one operation, by a single turn around thecontainer. 4 When the arrangements shown in Figs. 4 and 5 are employedthe strip 6 between the weakening lines I, 4, may be left uncoated withadhesive, or only lightly coated, the adhesion caused by the 40treatment with paraflln wax or other waterproofing agent being dependedon either entirely or partially to hold the two walls of the bodytogether at this point.

The blank I, with weakening lines according to these or other suitablearrangements, is rolled up to form a conical double-walled body. 2, anda,

closure of suitable form is secured at its smaller 9 end. The upper edgeof the body is turned over outwardly as shown at in on the left handside of I Fig. 1, and a suitable formation, suchas groove ,is impartedthereto. This turned over portion is, after the insertion of a closuredisc ii in groove it, turned inwardly, as shown at the right hand sideof Fig. 1, to secure the disc ll inplace.

The outward turning of the upper edge or the body, instead or the inwardturning usual in containers 0! this class, avoids the apron extendingdownwardly inside the finished container below the end closure II, whichis considered to be undesirable when the container is used for certainclasses of goods.

In Fig; 3 the end closure, instead 0! consisting oiaflatdiscasinFigJJsshownasadisc "having a flange i3, and is securely held inits place in the container by turning over the upper edge of the latterto surround such flange, and which upper edge in this case has notnecessarily been previously turned over outwardly, as when this methodoi. closing the container is employed there is no apron depending belowthe closure.

When it is desired to open a container formed as above described, thisis eiiected by tearing out the strip 6 between the weakening lines. asdescribed in the prior applications hereinbeiore referred to. This willseparate the upper end of the container with the closure attachedthereto, and this separated upper end can be subsequently used as a lidor cover it all the contents have not been taken out, the depending edgeof the separated cover portion fitting outside the upstanding edge 01.the inner wall leit by the removal 01 the strip 6, as shown mm. 2.

One or the advantages oi the present invention is that it will not benecessary to provide a separate cover to be used in case oi. need afterthe original closure has been removed, as the cover made integral withthe'container and separated as above described will serve veryeiiectually for this purpose.

What I claim and desire to secure by patent is:--

A paper container comprising a body having a double wall composed of aninner ply and an outer ply and provided at points spaced from one endwith weakening lines spaced apart and forming a strip therebetweenextending from end to end of the blank and the portion 0! which on theouter ply is of greater width than the portion thereo! on the inner ply,from which said wall is formed, the first named end oi. the wall havinga closure and being separated from the remaining portion of the wallwhen said strip is torn out, the body of said container being conical,said separable end portion of its wall being at the larger end thereofand after tearing of said strip and re-application oi the separable endportion to the body being adapted to at on the outer suriace oi theinner ply or the wall lett exposed by the removal or such strip andthereby adapt the cover to be refitted on the body wall after the striphas been torn out and the cover has been removed.
